Of Nakhon Sawan's 14 districts, 13 have a high estimated chance of river flooding and 0 a high chance of flash flooding. The highest risk is in Mueang Nakhon Sawan, where the river flooding level is High (estimated).
The 2024 observed flood event covers only four northern provinces (Chiang Mai, Chiang Rai, Lamphun, and Phayao); flash-flood terrain indicators are modelled from nationwide terrain data and are not a forecast. OpenStreetMap contributors

Mueang Nakhon Sawan in Nakhon Sawan has the highest single hazard estimate, a High level of river flooding.
Each district gets a Low, Medium, or High estimate for every hazard. "Observed" levels come from a directly measured event, such as a satellite-recorded flood extent. "Estimated" levels are modelled from proxies such as terrain, historical rainfall, or monitoring-station readings, and are not a forecast or a probability. A level never combines more than one hazard, and "Not enough data yet" means exactly that — not a safe rating.
A High estimate for Nakhon Sawan is a prompt to ask more questions — request a site-specific flood or engineering survey, check the property's ground floor level and past flood history with the seller or agent, and review local drainage before committing. A Low estimate does not guarantee a property is risk-free, and none of these levels replace a professional inspection.

The hazard estimates for Nakhon Sawan are sourced from Terrain-derived flash-flood indicators (HAND + slope + OSM drainage proximity; NOT a forecast or probability, not calibrated against observed events) from Copernicus DEM GLO-30 (via Mapterhorn terrain tiles) and OpenStreetMap waterway data. The banded metric flags whether the region CONTAINS terrain susceptible to flash flooding somewhere within it -- not the susceptibility of the region as a whole, and not of any individual property.

Low, Medium, and High are screening estimates, not a forecast or probability. Each hazard is scored on its own — there is no single combined risk score across hazards.
